This will allow you to play Unreal Tournament 3's Warfare mode with up to 128 players.

To install, unzip the content with a program such as WinZip or Winrar and copy into the My Documents / My Games / Unreal Tournament 3 folder (it will not over-write any existing files).

You will need to make one edit to one of your configuration files to allow the UT3 menu to accept the full 128 players. Locate your My Documents\My Games\Unreal Tournament 3\UTGame\Config directory, and open UTGame.ini. On the first few lines, in the Engine.GameInfo block, find MaxPlayers and set it to 128. The find the NumBots_Common and NumBots_DM data providers, and change their range data settings to MaxValue=128.

Note that this is a very early release, and is not polished in any manner.
